Atlas Sound MPFD24-3 – 3" Deep Micro Perf Door WMA 24RU Rack

Product Overview

The Atlas Sound MPFD24-3 is a 3" deep micro-perforated steel front door designed for the AtlasIED WMA, 100, and 200 Series wall-mount rack cabinets at 24RU capacity. The perforated steel mesh panel provides simultaneous ventilation for heat-generating equipment, visual reference to LED indicators and display panels inside the rack, and physical security against unauthorized access. The 16-gauge steel door frame delivers structural rigidity appropriate for a permanently installed wall-mount enclosure door. The extended 3" depth is specifically designed to accommodate rack rails positioned at the front face of the WMA cabinet while still providing adequate clearance for rack handles and security covers on installed equipment. TAA-compliant construction makes the MPFD24-3 appropriate for federal government and public sector AV system installations.

Product Description

Wall-mount rack cabinets in commercial AV installations face a recurring challenge: closed-door security and ventilation are opposing requirements. A solid steel door locks down the equipment and prevents tampering, but blocks airflow to rack-mounted amplifiers, DSP processors, and other heat-generating gear — causing thermal throttling or premature equipment failure. A completely open rack provides ventilation but eliminates access control. The MPFD24-3 resolves this with a micro-perforated steel mesh panel that allows substantial airflow through the door while maintaining a closed, secured enclosure appearance from normal viewing distances.

The micro-perforation pattern also serves an operational function: it allows LED status indicators, metering displays, and TFT or CRT screens on rack equipment to remain visible through the closed door. This eliminates the need to open the rack for routine status checks in managed AV systems, reducing the frequency of physical access and the associated risk of accidental equipment disturbance.

The 3" door depth is a deliberate specification choice. Many WMA cabinet installations position rack rails at the front face of the cabinet to maximize usable rack depth for deeper equipment. At the standard 1" door depth, this configuration can create clearance conflicts with rack handles, cable management hardware, or security lock covers that protrude beyond the equipment face. The MPFD24-3's 3" depth provides the clearance needed for front-loaded rack rails without requiring the rack rails to be set back, preserving full rack depth for equipment. The textured black finish with color-matched lockset provides a consistent, professional appearance. At 42" tall and 20" wide, the door covers the full face of a 24RU WMA cabinet.

Key Features

• Micro-Perforated Steel Mesh Panel — Allows ventilation for heat-generating rack equipment and visual access to LED indicators and displays while maintaining a secured, closed cabinet appearance.
• 3" Extended Depth — Provides clearance for rack handles, security covers, and cable management hardware when rack rails are positioned at the front face of the WMA cabinet.
• 16-Gauge Steel Door Frame — Heavy-gauge steel construction provides structural rigidity and resistance to physical distortion for a permanently installed wall-mount rack door.
• Ventilation and Security Combined — Micro-perforation design eliminates the need to choose between airflow and access control, supporting both simultaneously in a single door assembly.
• Color-Matched Lockset — Textured black finish with matching lockset provides a cohesive professional appearance and basic access control for the cabinet contents.
• Compatible with WMA, 100, and 200 Series Cabinets — Designed and tested for direct fit on AtlasIED WMA, 100 Series, and 200 Series wall-mount cabinets at 24RU.
• TAA Compliant — Manufactured in compliance with Trade Agreements Act requirements, suitable for federal government and public sector AV infrastructure projects.

Frequently Asked Questions

Q: What cabinet series is the MPFD24-3 compatible with?

A: The MPFD24-3 is designed to fit the AtlasIED WMA, 100 Series, and 200 Series wall-mount rack cabinets at 24RU capacity. For other rack sizes in these series, select the corresponding MPFD model with the matching RU count.

Q: Why does this door have a 3" depth instead of the standard 1" depth?

A: The 3" depth provides clearance for rack handles, security lock covers, and cable management hardware when rack rails are positioned at or near the front face of the WMA cabinet. This allows installers to maximize usable rack depth by front-loading the rails without creating a clearance conflict with the door.

Q: Does the micro-perforated door provide meaningful ventilation?

A: Yes. The micro-perforated steel mesh panel allows substantial passive airflow through the door panel, reducing heat buildup inside the cabinet for installations with amplifiers, DSP processors, or other heat-generating equipment.

Q: Can I see equipment status LEDs through the closed door?

A: Yes. The micro-perforation pattern allows LED indicators, metering displays, and screen-equipped devices to remain visible through the closed door, eliminating routine door-opening for status checks.

Q: Is the MPFD24-3 TAA compliant for government projects?

A: Yes. The MPFD24-3 is TAA compliant, making it appropriate for federal government AV infrastructure, GSA schedules, and other public sector projects subject to Trade Agreements Act requirements.

Q: What is the warranty on the MPFD24-3?

A: The MPFD24-3 is covered by AtlasIED's standard commercial product warranty. Contact Creation Networks or AtlasIED for current warranty terms and support procedures.
